Dears,
Just one question for RTC.
In SDK9.0, it's possible to control of time to use HW RTC block??
If possible, please let me know how to use it..
Thank you.
Lets say I have 200 bytes of data that I want to store in flash. So, I request a 200-byte block.
In order to store, the area has to be cleared first. As far as I understand...
